Would have been far more interesting to have just cut the scene, or just had Luke live with the idea Ben lied to him, manipulated him. It's the core problem with so much of ROTJ - trying to tie everything up in a nice neat bow for a happy ending. The darkly negative funk that started to seep in in the late 70s that manifests in ESB was trumped by the faux positivity of the beginning of Reagan era. SW has that post-Watergate, post-Vietnam need for euphoria but ESB is like the reflective hangover. Imagine if ROTJ had gone in the ESB direction - a saga that wraps up murky and sort of dark, instead of dancing with ewoks. Would have really been a much more modern-era movie.
